AI Technical Summary

Benefits of technology

The solution reduces the length of the water stop lip, improving workability and maintaining desired water stopping performance by using a plane abutment lip structure, which absorbs dimensional errors and ensures consistent sealing even with tolerance variations.

Problems solved by technology

In this case, there is a worry that there are variations in the wrap amount of the water stop lip 132 and water stopping performance cannot be maintained, so that a different technology is required.
The technology disclosed in JP-A-2005-349984 which adopts a similar structure has a similar problem.

Embodiment Construction

[0026]Hereinafter, a mode for carrying out the invention (hereinafter, referred to as “embodiment”) will be described with reference to the drawings.

[0027]FIG. 1 is a plan view showing a structure 1 for grommet attachment to a door panel 50 according to an embodiment of the present invention. As illustrated, in the grommet attachment structure 1 of the present embodiment, a grommet 10 is attached to a grommet concave portion (grommet accommodating concave portion) 52 formed on a side plate part A2 of the door panel 50. Further, a weather strip 90 is secured to the door panel 50 (the side plate part A2) so as to stride over the grommet 10. At this time, in the grommet concave portion 52, the entire surface of the part on the vehicle outer side of the weather strip 90 is covered with the grommet 10.

[0028]As shown in the plan view of the grommet concave portion 52 of FIG. 2A and in the cross-sectional view of FIG. 2B (IIB-IIB cross-sectional view of FIG. 2A), the grommet concave portio...

Abstract

On a back surface portion of a grommet, a clamp encircling water stop lip disposed around a first clamp insertion hole and a weather strip lower part water stop lip disposed in a position below a weather strip placement portion are provided. A first protector clamp protrudes from the first clamp insertion hole so that the first protector clamp can be locked in a first body locking hole in a grommet concave portion.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of PCT application No. PCT / JP2012 / 082965, which was filed on Dec. 19, 2012 based on Japanese Patent Application (No. 2011-281175) filed on Dec. 22, 2011, the contents of which are incorporated herein by reference. Also, all the references cited herein are incorporated as a whole.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a grommet and a water stop structure for a vehicle door using the grommet.[0004]2. Background Art[0005]Conventionally, as a water stop (waterproofing) structure for a door harness cabled on a vehicle door, a waterproofing structure has been known in which a through hole and a concave portion for a grommet are provided on an end surface (side plate) of a door frame hinge-connected to the vehicle body, the grommet attached to the door harness is fitted in the through hole and the door harness is cabled from the door to the vehicle body. In addition, various tec...
